Abstract
A heat-retaining moisture-transmissible water-resistant fabric which comprises (i) a fibrous substrate, (ii) a polymer layer having a multiplicity of interconnecting fine pores (layer A), formed on at least one surface of the substrate, and (iii) a polymer layer (layer B) formed on layer A, layer B contains 15 to 70 wt. %, based on the polymer of the layer B, of heat ray-reflecting fine metal pieces and has a multiplicity of interconnecting fine pores communicating from the surface to the interior and also has on the surface thereof fine pores, most of which have a size not larger than 5 .mu.m. The fabric may comprise, in lieu of layer B, (iv) a microporous polymer film layer (layer C), formed on layer A and having a multiplicity of interconnecting fine pores communicating in all the direction in the interior of layer C, most of which have a size of at least 1 .mu.m, and (v) a polymer layer (layer D) containing 10-70 wt. % based on the polymer of the layer D, of a heat ray-reflecting fine metal pieces and having on the surface thereof fine pores having a size smaller than 0.5 .mu.m and also having fine pores communicating with said fine surface pores, most of which have a size not …
